Graphs & what they tell us

Look at the graph shown here. The highlighted line is called the X axis and it represents the passage of time over which observations occur.

True

T/F A graph is a format for visually displaying data

True

Look at the graph shown here. What does this data tell us about the target response of reading words and the intervention procedure of reinforcement?

During baseline, the client did not read many words correctly. When reinforcement was used, the number of words read correctly increased and continued on an ascending trend.

Look at the graph shown here. What does the data point in red tell us?

The target behavior occurred 5 times during the 5th session

The graph we use most often in ABA is called

A line graph

What does the baseline condition show?

A measure of the target behavior before intervention is introduced

Which is an example of a possible confounding variable?

All of the above are possible examples of confounding variables that may influence a client's behavior

Which of the following statements is true about experimental control?

All of the statements above are true about experimental control

When a graph shows sudden or drastic changes in a client's behavior that do not seem to be attributed to anything in your session, it may be the result of a confounding variable. In this case you should...

Talk to the client's caregiver and try to figure out what the confounding variable could be. Show the data to your supervisor and discuss your concern. Don't do anything. Behavior changes unexpectedly sometimes and there is nothing you can do about it. both A & B

Which statement is correct about independent and dependent variables?

The independent variable refers to the procedure being used to change behavior, the dependent variable refers to the behavior being measured

What are the two situations in which a reversal (ABAB) design should not be used (select two answer choices)

When the data represents a skill that has been taught and cannot be unlearned When the behavior being tracked is a severe challenging behavior that may be dangerous or cause harm to the client or others

Which of the following statements is NOT true of a reversal (ABAB) design?

With a reversal design the baseline condition is implemented only one time

T/F An A-B design shows strong experimental control.

False

Which of the following is important when graphing?

Follow the graphing protocols outlined by the organization you work for Use correct terminology when writing on the graph Keep the graph clean and readable ALL OF THEE ABOVE

Which of the following is a reason that graphs are important?

Graphs allow for visual inspection of the data Analyzing data in graphic displays allows us to make more objective, data-based decisions Graphs help us demonstrate that the procedures we use are responsible for changes in the target behavior ALL OF THE ABOVE

What type of design is shown here?

Multiple baseline deign

Which best describes an alternating treatment design?

Multiple interventions are introduced repeatedly in an alternating pattern. These data are compared in order to determine which intervention is most effective.
